Of the 10,000 patent models held in this Museum, some 400 models are housed in and relate to the Graphic Arts Collection. These include models prepared for the printing, type, paper, and bookbinding trades.

The following Introduction is copied directly from Elizabeth M. Harris, Patent Models in the Graphic Arts Collection (Washington, D.C.: The National Museum of American History, Smithsonian Institution, 1997). This publication is illustrated with line drawings.

Black and white photographs of many of the 400 plus patent models in the Graphic Arts Collection were taken in the 1960s. We hope the publication of these photographs will also assist the public in better understanding the Collection.

“Until 1880, the U.S. Patent Office required most inventors to submit a model with their application for patent protection. The Patent Office thus became the keeper of a huge collection, one that suffered several catastrophes over the years. In 1836 a fire at Blodgett's Hotel, where the Patent Office was housed, destroyed all existing models—about 10,000 items—as well as the records of some specifications. After the fire new patents, hitherto unnumbered, were numbered in a consecutive series. In 1840 an effort was made to restore models and specifications lost in the fire. Some 2845 were restored (and numbered in a new X... series), but there were gaps that could not be filled and remain blank to this day. In 1887 a second fire started in a loft in the Patent Office where 12,000 rejected models were stored. It spread rapidly, destroying or damaging 114,000 more models out of the total collection of around 200,000. Of these, 27,000 were eventually restored, while 87,000 were lost.

The first patent models now in the Graphic Arts Division came to the Smithsonian in 1908—a group of eleven models transferred by the Patent Office. In 1926 Congress decided to dispose of the remaining Patent Office collection, which then consisted of some 150,000 models. About 10,000 pieces came to the Smithsonian's U.S. National Museum.

The largest single group within that transfer—about 4,000—consisted of models for the textiles industry. More than 300 were for the printing trades. Other printing models have arrived since 1926, singly or in small groups.”

This patent model demonstrates an invention for a mold that made blocks that were used in printing carpets or wall paper; the invention was granted patent number 10630. The design, formed of short and long pieces of type, was set up in a square casting box. The printing block was then cast in any suitable material such as type metal, plaster-of-paris, vulcanized rubber, or, by preference, gutta percha - a popular material in the mid nineteenth century.

This patent model demonstrates an invention for a shooting stick, used for driving in quoins, or wedges, to tighten a form in its chase; the invention was granted patent number 107154. These sticks had different-sized notches to fit different quoins, and two wings to help open spaces for the quoins among the furniture.

This patent model demonstrates an invention for a metallograph, and was granted patent number 215792. With this tool, a writer could turn a sheet of metal into a printing plate as he wrote on it. The air-powered writing instrument made a series of sharp blows to the metal, knocking out projections on the back of the sheet. The projections formed a facsimile of the writing in reverse and in relief for printing at a type press.

This patent model demonstrates an invention for a card guage for a platen printing press; the invention was granted patent number 145101. This invention provided a card feeder for Golding's Pearl press, which was covered by a patent of 1871 taken out by William L. Balch and assigned to Golding and his partner Edward Dennison (Patent 118182). William Golding (1845–1916) was apprenticed to a printer at the age of 15, and set up The Printer Manufactory Company at 23 with his partner, Edward Dennison. The company at first supplied stamps and seals and other stationery goods, but soon moved into the manufacture of small presses for amateurs, such as the Pearl, and then full-sized jobbing presses. Two years after Golding's death, the company was sold to the American Type Founders Company, which continued the manufacture of his presses for some years.

This patent model demonstrates an invention for a combination of quoins and sidesticks which was granted patent number 218518. The quoins swiveled on the ends of wide screws that turned into the sides of the metal sidesticks. A guage in the center of each sidestick told the compositor how far the quoin could be extended.
